Write_Parameter - Siemens SIMATIC NET IE/AS-INTERFACE LINK PN IO Manual

8 Using the Data Record Interface
8.2.2.3

Write_Parameter

Meaning
The parameters transferred with the call are passed on to the addressed AS-i
slave. The parameters are stored on the IE/AS-i LINK only temporarily and are not
entered as configured parameters in the EEPROM!
The AS-i slave transfers its status value in the response as parameter echo. The
response can deviate from the value that has just been written according to the
AS-i master specification (/2/).
Exceptions
There are some AS-i slave types with which the AS-i master itself manages the
slave parameter assignment. The configured parameters for these AS-i slaves are
always the same F
parameter assignment itself.
